Ancient NAR Motor Data C5-3
 

Does anyone have a copy handy of the NAR motor test results?

Estes C5-3 or Centuri C5-3S (same motor)

I'd like to compare it with other actual NAR data, not catalog specs.

I'd love to see an NAR graph too!

I know I have one but have not been able to find it.
May be on a very old laptop...will check that next.

Much appreciated!

Is this real NAR data?

It's actually still on the NAR site....I just had to change the file name manually. https://www.nar.org/SandT/pdf/Estes/C5.pdf

The same trick didn't work for B14s however.

Now I'm curious about real tested B14's, especially the older ones.

It did for the B8, though. :cool:

I did the same check last week. I was going to contact NAR and see if the old test data for B14s is available for “research” purposes.

I've set up a spreadsheet to compare Total, Peak, and Avg thrust with clusters to compare them with larger single motors. I'd love to compare some clusters to real B14 data. Of course, that's only if they provide an early enough example that shows it's a real B14 instead of a rebadged B8.

I'm almost positive I can successfully fly Saturn V on a triple B6-2 or B4-2 cluster! Peak thrust is greater than a single D12 and total impulse is only a few ticks lower. Probably would only get 75 ft!!!! :chuckle: :D :chuckle: :D

I have the B8 data on my computer.... :)

I just finished downloading all the Estes and Quest PDFs, including the B8 and C5 since they include a little more info than I put in my spreadsheet. Now if they discontinue another motor, I'll have it forever. I won't remember I've got it, but I'll have it! :chuckle: :eek:

Setting up a spreadsheet is a great idea. Makes it easy to compare trade offs in motor choice.

I have all the NAR motor files bookmarked, so I can look up average thrust and peak thrust on all the motors I use, as well as have, or may want to buy. This is especially important since I’ve found motor designations to be wildly off for some motors. The worst examples I have are the Aerotech 18/20 reloads I use on my Mars Lander. I decided on the D13 initially, thinking the D24 may have too much kick. Turns out the D24 is really a D15 (average thrust of 14.77N vs. 12.67N for the D13). I’ll try a D24 next flight. The Mars Lander just screams on a D13, by the way.

found this link of rasp data B14s are listed

David,

That makes the B8 look pretty decent. I have a 3-pack of B8-5s. I’ll have to do a B6-B8 test next time I go launch. I bought them years ago, but honestly don’t remember if I’ve flown any B8s before.

B8s give a quite noticeable extra kick off the pad vs. B6s - it's fun. I am seeing a similar look of late flying Q-Jet C12s.

Hmmmmmm.....next time I'm up at Sixty Acres flying on my own I should fly a B8-5 in a Nova Payloader with an AltimeterThree and then compare acceleration curves......:D Or maybe I should write to Steve Lubliner and get official permission to fly B8s at the next WAC launch (weekend after this one upcoming). I have about a dozen and a half of them that I got from Rich O'Hara shortly after I BAR'd, coming up on 10 years ago now ( :eek: ).

The raw rasp data pulled from r.m.r. left a little something to be desired. I jumped back on the NAR testing page and modified the URL to get all of the NAR test data on FSI motors. The composite G60 is missing, but everything else is there. The F100 is listed as an F80. We've all heard it was a baby F. Well, it's barely an F at 42.68N-s!

All testing was done in late 1994-1995. I thought Harold Reese died in 1993, so the test dates are interesting.
